Line Up and Wait
When I monitor a Freq on COM1 and transmit on COM2 (KX155) I get loud feed back transmitting and it sounds like I am screaming in my own ear.
This does not always happen (I regularly transmit on ground on COM2), and I only noticed it on the last flight. This was a night flight below freezing if it matters and my wife was constantly twiddling with the squelch (but that didnt seem to fix anything).
Setup is a Garmin 340 audio panel with GNS530 COM1 and KX155 COM2 and Bose A20 headsets (battery power).
Any ideas what to check next?
I have not tried to cycle panel lights off yet but I am pretty sure I have used COM2 on ground at night with out issue since this is my normal procedure (Awos/Ground on COM2 - Approach/Tower on COM1) and would have noticed.
